2) Installing a newer version of BOINC never used to cause a PC to detach from the project. Can we please return to this state?

Upgrading to a new BOINC does not detach you from your projects. But what can happen is that the data is not migrated to the correct place, or you put in a wrong place for the Data directory to be in, one that BOINC is not allowed to read.

Please post a question of help about that anywhere else, let's not do that in this thread. I am sure that the old work is still on your computer and it could possibly be gotten back. Jord

Ancient Astronaut Theorists suggest that in many ways, you can be considered an alien conspiracy!

But then there's problem 2. An application download checksum error (a) doesn't cause exponential backoff and (b) causes all workunits also requested by this particular client to be errored out and resent.

This would explain why I have processed virtually nothing for the past month while my computer has been running almost 24x7?! After a week of processing an AP WU it gets errored out?!

@ Batman

Not the same problem as yours.

In the problem Matt was referring to, no processing could be done because the application which does the crunching had not been downloaded yet.

If you did a week of processing then you must have already downloaded the application!

[edit] BTW, I still think these rollouts should only be launched earlier in the week. [/edit]

Astropulse v5 was rolled out Wednesday February 11 at about 5 pm Berkeley time. No obvious problem for 9 days, then whammo!

Joe

Thanks Joe.

I certainly agree with the whammo bit, but what changed? Did we just hit some limit or tipping point in the system after 9 days that suddenly pushed things over the edge? Things just don't suddenly go bump in the night by themselves.

Oh well, as has been correctly pointed out by many, there is no lack of other projects to run.

So I suspect it wasn't a deliberate change, but a tipping point - the only other possibility is that I think I've seen an increase in the amount of Astropulse_v5 v5.03 being sent out, perhaps as Astropulse v5.00 WUs clear out of the database, which might have nudged the system into instability.

Maybe if CNS finishes up drawing up the plan to get Gigabit Ethernet between Hurricane Electric and the Space Sciences Laboratory, maybe it could submit the plan to compete for the stimulus package money :-D . (The closest SONET speed near one gigabit would be OC-24, but that speed is apparently not commercially viable. The closest commercially viable speed apparently is OC-48.)

However, it would be a long shot, because California probably needs all that money to stay out of needing to file for bankruptcy due to the subprime mortgage crisis that started in California and Florida that is currently destroying the tax base.

In my view, the tipping point came right after Lunatics released the new optimised AP 5.03 app, then everyone started downloading new AP WUs to run on the new (r112) opt app.

I myself am making a specialty of running only the older AP opt app (r103) and cleaning up many of the old-version WUs that are being returned late or aborted. I am keeping my 4-day cache filled easily.

Three cheers and thanks to those wonderful, skilled programmers who can take full advantage of the CPU hardware features and get both MB and AP WUs to complete in half the time. THANK YOU !!!

Although some of us have been running r112 since 13 February in an attempt to confirm accurate validations (unfortunately v5.03 was never tested at Beta, so no pre-release validation tests could be carried out there), I don't think you can say that the Lunatics release 'caused' this event.

[We did think of claiming that the release timing was deliberate - "download from Lunatics if you can't get an official copy from Berkeley" - but that would have untrue: the timing was pure coincidence].

BTW, congratulations on the effort to clean up v5.00 - but it is possible to run both versions together until the cleanup is complete.

Over 1500 Mahalos to You! Tanks yea for all you guys doing. Also hope we can help for make more bandwidth. Everything seems 5x5 now. Got all work uploaded and got nearly full caches on all 3 machines. Woo hoo, life is good.
